It looks like if literal character sets were changed from (<string>) to something like (literal-charset <string>), then sequences would not need to start with : or seq. The grammar for sequences could change from (: <sre> ...) to (<sre> ...). I think that it would look cleaner, but then I am something of a heretic.

First, please understand this is an established notation with a

long history and in active use. We would need a convincing

argument to change the notation now, not superfluous stylistic

changes.

In this case I think it looks less clean, because it moves away

from the prefix notation.

For consistency with R7RS #!fold-case and #!no-fold-case, I suggest changing these to be w/no-fold-case and w/fold-case.

Similarly for this and for prefixing boundary assertions with @,

I don't see the benefit.

Others are free to chime in if they think such changes would

really be worthwhile.
